Hallo I'm new to this site. I'm here because I love my wife young sister, she have a son of one year and her boy chased away. She was staying home (parents) and this year I helped her to get a job and she work as my assistant at my office and we both stay together. She look familiar with my wife and is very difficult to differentiate them. I'm looking for the right spell which will make her change is mind and be in love with me because right now she is afraid of her sister and we are not in good communication.

You need to work this out on your own. If you depend on a spell, and have never done a spell in your life, you might not get the results you want and it could possibly harm you later on in the future.

You cannot just come on here, ask for a spell and do it. You must know the basics of magic if you wish to use it. You must respect it and understand it. Not just chant some words and think it will work. It does not work like that.
